Be it known. that I, Gnone Gernma subject of the German Emperor, an'da resident of' Berlin, Germany, have invented certain new and useful improvements in VVater- Motors for Utilizingthe Ebb and Flow of the Tide, of which the following is a specification.-

' This invention relates to water-motors of that in which the ebb and flow of the tide are utilized for obtaining driving power, for "which purpose there is provided In a backwater reservoir a turbine, the working of which depends on the rising and falling of the level of thewater-in the reservoir, and this reservoir has an outlet'into a lower-situated reservoir with a lower water-level, and the power produced by the water rushing in is transmitted to the place where it usual means. r p p The essential featureof the invention consiststherein that the piston of awaterressure cylinder is used for carrying the tur in'e;

The flowing in and flowing out of the water in the cylinder is regulated by afloat in frontof-the turbine in'accordance'with the level of the water in the/backwater reservoir for the ebb-water, which float is constantly followed by the'turbin'e by means of a screw-thread or the like provided on a telescoping rod rigidly connected with'the plug of theregu-lating-cockpit thewater-pressure cylinder, and

the flow, is regulatedln a manner that the turbine only very gradually rises and sinks according to the gradual rising and sinking of the water-level. I

Figure 1 shows the whole plant in a side view and partly-insection. Fig. 2 shows a horizontal section throughthe same. Figs. 3

and 4 are detail views. Figs. 5 to 7 show the manner against theinrush of the water by the auto1naticallyclosing valves 0 or the like,

. while the tide-water is conducted to the reservoir I) through the valves (1 opening into the same. The 'water will consequently stand higher in the reservoinb than in the reservoir a, so thatthe water-wheel of a tur- 'laine g, likewise arranged in .a manner already knownhetween the two reservo rs fed by mtail'r fwm the reserveirffi, f e put...iiita iota:

ings) is use whose movement is automatically re ulated by the following device. On

the guiderframe w,which rigidly connects the piston-rod of the piston f with the Uurbineg, is rigidly fastened anarn'i Z, extendinginto the reservoirib, in Which there is guided a rod connected with the float u, and

can be moved up andfdown, but not be turned infthe same. To the lower end of this rod is rigidly connected the slide v, which vided with. a screw-thread, a rod t, fastened encompasses at its upper end, where itis pro-- with its upper. endto the arm Z turnably,.but

not slidably, which 'ro'd can belengthenedand shortened-after the manner of a telescope: The rod t, whose two" sliding parts cannot be turned one on theother, owing to a the arrangement that a projection on theone 'part engages a slit in the other. in a manner already known and which-will therefore not be describedhere, so that on the one part 'be-.-

ing turned the other is turned likewise. This rod-t, made Water-tight, passes through the bottom of the reservoir b andout of the same i at r. The lower end ofrthe rod t is rigidly connected to the plug'of the-threewvay 000 n, provided between'the water-pressure cylinder and the forcing-pump. From this three-way cock leads the way '0 to the forc- -ingpurnp, the way q to the space below the piston f of the water-pressure cylinder, and I the way p to the water-reservoir of the fore- --ing-pump or to any other outlet.

The workingof thisplant is as follows On the flood coming in'the' float ucommences to roo rise a little and to. move ahead of'the-tur bine. As the arm l-prevents itfrom moving sidewise and it can thusonly risevertically and as, further, theslide'v is rigidly connected to the rod of the float and is guided on the rod 13 or-the thread 8, so'that it likewise cannotmove out ofthe way, but must, the same as the float, ascend exactlyperpendicularl. itmust' act on the screw-thread s of the ro t in a',manner that it willturn, b means of the 3" I uprger as wel as the lower; zparjtgof the rod-t an 0th in the same dlrec water-pressure cylinder. In consequence of this the turbine g is raised a little by the warod t, for it during u, andthe float cannot 'yield. In conse- 2 back into the position shown in Fig. 5

tion, as these parts cannot turn one upon the other. By this turning of the rod t, which is preferably so calculated that, in consequence of a corresponding slant of the screw-thread, it is forty-five degrees, the three-way lug of the cock nis turned in the direction 0 the arrow 1, Fig. 5-, ,and gets into the position Fig. 6, whereby there is established acommunication between the way 0, coming from the forcing-pump, and the way g, leading to the ter coming from the forcing-pump through the plug of the cock and the way q and acting on the piston f, so that the turbine follows the float, and the height of the fall becomes equalized again. In order to allow of this upward movement of the turbine, it must be possible to lengthen the rod t; but in order that the water should not act any further after this upward movement of the same'and press it above the level of the water provision has been made in the present invention that the cock n is at once closed again when the turbine. has moved upward only a small step of its whole upward movement, and so on aftereach small upward movement. This is again effected by the screw-thread s of the the short upward movement of the turbine also the upper part of the rod t, which is turnably connected with the arm Z, is raised the rod t is turned by the screw-"thread s, in the opposite direction, as

this thread must'wind its way through the slide 11, which is rigidly connected to the float (1111161106 of this the lower part-of the rod 25 turns t e plug of the cock n out of the position shown in Fig. 6 in the direction of the arrow that is'to' say, it blocks the way of the pressure fluid to the pressure-piston f, so that the turbine cannot be raised any further and not be driven'above the level of the water. The just-described processes are repeated in succession during the, tide. If now the. ebb follows, the float 'u sinks. It is to be presumed here that the slide a) when the tide is highest has its position about in the middle ofthe screw-thread s, which corresponds with the checking position of the plug of the cock )2. (Shown in Fig. 5.) It now the floats sinks, its slide-'vturns the rod t with the cooperation of its screw-thread in a'manner that the plug of the cock n is turned in the direction of the arrows 3 (shown in Fig. 5) and into'the position shown in Fig. 7, whereby there is established a communication between the waterpressure cylinder through the tube g with ti. on "t-tube p for the pressure-water, so

" lYitnesses:

tin. a .crtain part of the waterbelow the piston passes out, and the turbine sinks acorresponding distance; but as the float 11. does not sink so rapidly, and conse uently also the slide 1), rigidly connected tot e float u, does not change its posi turbine, the screw-thread s of the. rod t on the latter being shortened must Wind itself again through the slide Z) in the opposite direction back to its previous position; but in doing so it turns the rod tin a manner that the plug is turned again out of, the position shown in tion quite as rapidly as the Fig/7 in the direction of the arrow 4 back into the position shown in Fig. 5, and thereby stops the flowing out of the pressure-water from the water-pressurev cyhnder in order that the same does not become quite empty, in consequence of which the turbine would sink in a moment, or at least much too rapidly. which might damage'and throw out of order the whole installation. The rising as well'as thev sinking of the turbine is therefore effected only gradually, or-by steps, so that'whenlthe float sinks-only a little the cockis opened only. so far that but a small quantityof water can run out, whereupon on the subsequent sinking of the turbine, however small it may be, the cockfor stopping the exit of the pressure-water is at once closed, which process is repeated step by step until the turbine has reached its lowest position.-
